▎ 摘  要

NOVELTY - The super capacitor has an anode provided with a positive current collector and a positive electrode active layer that are combined on a surface of the positive current collector. A cathode is provided with a cathode current collector and a cathode active layer that are combined on the surface of the cathode current collector. The length of the anode active layer is positive. The width of the anode active layer is positive. The length of the cathode active layer is negative. The width of the cathode active layer is less than 1.5. The first active material or second active material includes activated carbon, activated carbon fiber, capacitive carbon, graphene, carbon nanotube and graphite. The first adhesive or second adhesive includes polyvinylidene fluoride, polytetrafluoroethylene, styrene butadiene rubber, sodium carboxymethyl cellulose, sodium alginate, and polyacrylic acid. USE - Super capacitor. ADVANTAGE - The super capacitor has high capacity retention rate and internal resistance stability, excellent cycle performance, and can effectively avoid generating gas phenomenon in the super capacitor charging and discharging process. The super capacitor ensures the stable performance of the prepared positive electrode and the negative electrode so as to ensure the stable performance of the prepared super capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a super capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of super capacitor.
